I found an old computer on a Finnish auction site today. It's described as a Unix-computer made by NCR in the late 70s/early 80s. It has A3-sized memory modules and a tape drive. It's size is 60x12x65 cm and it weighs 37 kg. No other information is available, but 5 photos of the machine is available at cs.helsinki.fi/u/mvvuorel/nixi/.

Can I run Open/Net/FreeBSD on this machine? I'm pretty sure I could get it for 1€, and it would be fun to try something other than x86 and x86-64.

I did find these emails to the NetBSD mailing list, unfortunately it would appear that no port to this system exists yet.. the CPU (..m68k) is supported, but the rest of the systems hardware may be completely undocumented and NCR proprietary.
